TO ALL WHOM vIT MAY CONCERN:

Be it known that I, CELRICE, ofPort Henry, in the county of Essex, and State of New York, have nYentcd n new and improved Boot-Crimping Muchineg--and I do hereby declaro that the following is a.` full, elettr, and ex'acfl description thereof, which will enable those skilled in the'art to make and use the same, reference-*being had to the accompanying plate of drawings, forming part'of thisspecification.

This' invention relates to a new and improvedniaohinefor crimping boots, Iand Vit consists of a series of` rotary trees, in connection with a'pluralityof jaws o1' pressure-planos, all constructed fand arranged in`such a way as to admit'of boots being crimped rapidly, and in a perfect manner. VIn the alccompanying plate of drawingsy Figure 1 is a side vertical view of my invention, taken' in the line fig. 2.'

Figure 2, c. plan or top view of the same. 1

lligure, a transverse verticaly section of the same, teken in Vthe line y y, fig. 2.

Similar letters of reference indicate correspondng parts. Y 5 i A represents the frame ofthe machine, which uiny be constructed of wood or nletalfand B is a shaft, placed transversely on said frame, und having four bootltreos, VC, attached, which are of rectangular form, and all connected, the inner or leg portions, a, being radial Vwith the shaft D, andthel foot portions, I, being at rightfnngles with rtheleg portions, a, as shown Ycloarly'in lig. l. These trees are constructed of iron, and they have a. rotary lnotion communicated to .them vby means ofa. crank, c, and gearing@ d, as shown clearly in lig. 2. D D D and D DP X DXXXiepr-e'sent jaws or pressurcpates, which are designed to be of cast iron,

their outer edges forming portions of a circle. 'Those jaws .or plates' are rranged in pail-53D being opposite to or by the side of 'D X, D by the side of DXX, and D by the side of DXVXX., (sce figs. 2 and The inner' `surfecesof these jaws or pressureplntes are provided with ribs e, and each jun' orpln-t'e hastwo'arnns or shafts,

f', which pass loosely through the sides of the frame A, and fare allowed to slide freely therein. In `the sides l ofthe frame A screws' g are fitted loosely, each screw haringen Indie-rubber spring,v L, upon it, said springs fitting on thescrews like nuts. The inner ends of thcscrews g'bear' against the jaws'or pressure-plates, and, by turningror adjusting the springen, a greater or lesspressure-ot' thejaws or plates against the leather, on the trees may be obtained, as desired. :The leather is adjusted on the trees C, and the latter rotated so as'to press between the ja-ws or pressure-plates, the latter smoothing or crimping the leather, and adjusting it snuglly on the trees, so that the-work' will be donc in a perfect manner.

Having thus described my invention, Iclairn'as new, and desire to secure by Letters Patent-- The rotaryfboot-trees C, in combination with thefjaws onpressure-pletcs D D D, DXDXXDXXX, all being constructed and arranged'to operate in the manner substantially ns'and for the purpose slet forth.
